All the time
My wife on her 650 and me on my 800 just completed a 5,500km ride through inland Australia. Around 3,000km of this ride was on dirt roads and tracks. This ride took us 3 weeks and we camped out most nights. This ride took place in August and at that time in Australia is was at 0.0 Celsius most nights. The 650 performed flawlessly as did the 800. My wife had been only riding bikes for 18 months, and there was the slight doubt in my mind about the difficulty of the journey. It was an epic and almost life changing experience for us both, we are now eagerly planning our next venture up yo the Gulf country.
